The longitudinal curb drainage ditches are connected to the roadbed side ditch outside the tunnel.

[0003] In existing technologies, the conventional function of cavern drainage systems is to guide flow. To ensure a consistently good flow guidance effect, filtration structures are typically installed in the drainage system to periodically remove impurities filtered during the flow guidance process, thereby meeting the drainage volume requirements. However, existing cavern drainage diversion devices have the following technical problems: It is not conducive to the installation of filter structures, and when existing filter structures are filtering debris, the debris is prone to move in the opposite direction due to the collision between the drainage and the filter structure, which is not conducive to the filtration and recycling of debris. Utility Model Content

[0004] The purpose of this utility model is to provide a cavern drainage diversion device to solve the problems of existing technology which is not conducive to the installation of filter structures, and the existing filter structures are prone to collision between drainage and filter structures when filtering debris, causing debris to move in the opposite direction, which is not conducive to the filtration and recycling of debris.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tunnel drainage diversion device includes longitudinal curb drainage ditches set on both sides of the tunnel, and transverse drainage ditches set at both ends of the tunnel and connected to the longitudinal curb drainage ditches, as well as covers set on the longitudinal curb drainage ditches and transverse drainage ditches. The longitudinal curb drainage ditches and transverse drainage ditches are provided with grooves and inclined grooves set adjacent to the grooves. Filter structures are set in the grooves and inclined grooves. The inclined grooves are set at the front end of the drainage diversion direction and the inclined grooves are located at the high end of the grooves. The filter structure includes a first filter screen groove with an opening at the top, which is placed in a groove, and a second filter screen groove which is disposed in an inclined groove, connected to the first filter screen groove, and with an opening on one side of the first filter screen groove. The top of the second filter screen groove is in contact with the cover.

[0006] Furthermore, the second filter slot has an opening at the top.

[0007] Furthermore, the bottom and sides of the first and second filter screen grooves are connected; A locking block is provided on the outer side of the side where the first filter screen groove and the second filter screen groove are connected. The longitudinal curb drainage ditch and the transverse drainage ditch are equipped with slots that cooperate with the locking blocks.

[0008] Furthermore, at least one rotating shaft is provided on the opposite side of the middle of the first filter screen groove and above the first filter screen groove. A rotating sleeve with blades is rotatably mounted on the rotating shaft at intervals. When there is one rotating shaft, it is located on the opening side of the first filter screen groove. When there are multiple rotating shafts, they are arranged longitudinally upward from the opening side of the first filter screen groove.

[0009] Furthermore, the blades of the rotating sleeve are provided with filter holes.

[0010] Furthermore, multiple sets of limiting blocks are equally spaced on the rotating shaft, and the rotating sleeve is disposed on the rotating shaft between each set of limiting blocks.

[0011] Furthermore, when there are two or more rotating shafts, the rotating sleeves on adjacent rotating shafts are staggered.

[0012] Furthermore, grooves and inclined slots are equally spaced within the longitudinal curb drainage ditch and the transverse drainage ditch.

[0013] Compared with the prior art, the advantages of this utility model are: I. This utility model sets up grooves and inclined troughs adjacent to each other in the longitudinal curb drainage ditch and the transverse drainage ditch, and can quickly install matching filter structures on them. When the drainage is diverted, the sewage will first flow through the first filter screen trough in the groove, and then through the second filter screen trough. Some of the debris will flow into the first filter screen trough to be filtered, and some will be filtered by the second filter screen trough. Since the inclined trough is located at the high end of the groove, even if the flow rate of the drained water (referring to the drained sewage) is relatively fast and collides with the end of the second filter screen trough, pushing some debris to move in the opposite direction, it can be effectively blocked by the high end of the inclined trough, so as to facilitate the filtration and recycling of debris. 2. The top opening of the second filter screen groove is defined in this utility model so as to facilitate the quick cleaning of debris in the second filter screen groove; Third, the purpose of setting slots on the longitudinal curb drainage ditch and the transverse drainage ditch, and setting a block on the outer side of the side where the first filter screen groove and the second filter screen groove are connected, is to facilitate the more stable installation of the filter structure in the groove and the inclined groove. Fourth, this utility model has a rotating shaft in the middle of the first filter screen groove, and a rotating sleeve with blades on the rotating shaft. The purpose is to reduce the impact force of the drainage, that is, to effectively prevent the drainage from impacting the second filter screen groove and causing the debris to move in the opposite direction. At the same time, it can also effectively block the debris entering the first filter screen groove and prevent it from being carried out by the drainage. V. The purpose of setting filter holes on the blades in this utility model is to prevent the blades from having an excessive impact on drainage; VI. This utility model limits the rotating sleeve between each set of limiting blocks to prevent the rotating sleeve from moving along the length of the rotating shaft under force, causing multiple rotating sleeves to come into contact and affecting drainage on one side. VII. When there are two or more rotating shafts, the rotating sleeves on adjacent rotating shafts are staggered. This is to increase the contact surface for drainage and also to effectively prevent the backflow of debris that enters the first and second filter screens. 8. The present invention defines that the grooves and inclined slots are set at equal intervals in the longitudinal curb drainage ditch and the transverse drainage ditch. The purpose is to facilitate the filtration of debris in the drainage at equal intervals, which can share the debris that the subsequent filtration structure needs to filter, so as to avoid the problem of rapid blockage. It also makes it easier for cleaning personnel to quickly find the cleaning point. Attached Figure Description

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Example 1 To address the problems of existing technologies being unfavorable for installing filter structures, and the tendency for existing filter structures to cause debris to move backward due to collisions between the drainage and the filter structure during debris filtration, thus hindering debris filtration and recovery. For example... Figure 1-5 As shown, a tunnel drainage diversion device is provided, including longitudinal curb drainage ditches 5 set on both sides of the tunnel, and transverse drainage ditches set at both ends of the tunnel and connected to the longitudinal curb drainage ditches 5, as well as covers set on the longitudinal curb drainage ditches and transverse drainage ditches. The longitudinal curb drainage ditches and transverse drainage ditches are provided with grooves 1 and inclined grooves 2 arranged adjacent to the grooves 1. A filter structure 3 is set in the grooves 1 and inclined grooves 2. The inclined grooves 2 are set at the front end in the drainage diversion direction, and the inclined grooves 2 are located at the high end of the grooves. The filter structure 3 includes a first filter screen groove 4 with an opening at the top in the grooves 1 and a second filter screen groove 6 set in the inclined grooves 2 and connected to the first filter screen groove 4 and with an opening on one side of the first filter screen groove 4. The top of the second filter screen groove 6 is in contact with the cover.

[0025] In practice, when treating longitudinal curb drainage ditches and transverse drainage ditches, it is necessary to first set adjacent grooves 1 and inclined grooves 2 on them. After setting them up, the first filter screen groove 4 of the filter structure 3 is placed in the groove 1, and the second filter screen groove 6 is placed in the inclined groove 2. Then, the cover is placed on the longitudinal curb drainage ditch and transverse drainage ditch, and the filter structure is placed under the cover. In this embodiment, by setting adjacent grooves and inclined grooves in the longitudinal curb drainage ditch and transverse drainage ditch, and quickly installing matching filter structures on them, when draining, the sewage will first flow through the first filter screen groove in the groove, and then through the second filter screen groove. Some debris will flow into the first filter screen groove to be filtered, and some will be filtered by the second filter screen groove. Since the inclined groove is located at the high end of the groove, even if the flow rate of the drained water (referring to the drained sewage) is relatively fast and collides with the end of the second filter screen groove, pushing some debris to move in the opposite direction, it can be effectively blocked by the high end of the inclined groove, so as to facilitate the filtration and recycling of debris. The first filter screen groove 4 and the second filter screen groove 6 can disperse debris, effectively preventing debris from accumulating in one place and affecting drainage efficiency. Furthermore, the inclined groove 2 and the recessed groove 1 are set in places lower than the longitudinal curb drainage ditch and the transverse drainage ditch, so debris in the first filter screen groove 4 and the second filter screen groove 6 is more likely to accumulate in these places, which is more conducive to extending the cleaning time.

[0026] Example 2 Based on Embodiment 1, the top opening of the second filter screen groove 6 is designed to facilitate the quick cleaning of debris in the second filter screen groove.

[0027] Example 3 Based on Embodiment 2, the bottom and sides of the first filter screen groove 4 and the second filter screen groove 6 are connected; a locking block 7 is provided on the outer side of the side where the first filter screen groove 4 and the second filter screen groove 6 are connected; and locking grooves 8 that cooperate with the locking block 7 are provided on the longitudinal curb drainage ditch 5 and the transverse drainage ditch. The purpose of providing locking grooves on the longitudinal curb drainage ditch and the transverse drainage ditch, and providing locking blocks on the outer side of the side where the first filter screen groove and the second filter screen groove are connected, is to facilitate a more stable installation of the filter structure in the groove and the inclined groove.

[0028] Example 4 Based on embodiment 3, at least one rotating shaft 9 is provided on the opposite side of the middle of the first filter screen groove 4 and above the first filter screen groove 4. A rotating sleeve 11 with blades 10 is rotatably arranged on the rotating shaft 9 at intervals. When there is one rotating shaft 9, it is arranged on the opening side of the first filter screen groove 4. When there are multiple rotating shafts 9, they are arranged vertically upward from the opening side of the first filter screen groove 4.

[0029] In practice, as drainage flows into the first filter screen trough 4 and / or impacts the rotating sleeve 11 on the rotating shaft 9, some debris directly enters the first filter screen trough 4, while the remaining debris is blocked by the rotating sleeve or rotating shaft (the rotating sleeve's rotation consumes momentum when drainage impacts it, thus reducing the impact force of the drainage). Some debris entering the first filter screen trough 4 is carried into the second filter screen trough 6 by the drainage flow, while most debris remains in the first filter screen trough 4 due to the obstruction of the rotating sleeve or rotating shaft. In this embodiment, a rotating shaft is positioned in the middle of the first filter screen trough, and a bladed rotating sleeve is mounted on the rotating shaft. This is to facilitate the reduction of the impact force of the drainage, effectively preventing the drainage from impacting the second filter screen trough and causing debris to move in the opposite direction. Simultaneously, it effectively blocks debris entering the first filter screen trough, preventing it from being carried out by the drainage.

[0030] Example 5 Based on embodiment 4, the blades 10 of the rotating sleeve 11 are provided with filter holes 12. The purpose of providing filter holes on the blades is to prevent the blades from blocking drainage over a large area.

[0031] Example 6 Based on embodiment 5, multiple sets of limiting blocks 13 are equally spaced on the rotating shaft 9, and rotating sleeves 11 are disposed on the rotating shaft 9 between each set of limiting blocks 13. The rotating sleeves are confined between each set of limiting blocks to prevent the rotating sleeves from moving along the length of the rotating shaft under force, causing multiple rotating sleeves to come into contact and affecting drainage on one side.

[0032] Example 7 Based on Embodiment 6, when there are two or more rotating shafts 9, the rotating sleeves 11 on adjacent rotating shafts 9 are staggered. The purpose of staggering the rotating sleeves on adjacent rotating shafts when there are two or more rotating shafts is to increase the contact surface for drainage and to effectively prevent the backflow of debris entering the first and second filter screen grooves.

[0033] Example 8 Based on Embodiment 7, grooves 1 and inclined grooves 2 are equally spaced within the longitudinal curb drainage ditch 5 and the transverse drainage ditch. The purpose of defining the grooves and inclined grooves as equally spaced within the longitudinal curb drainage ditch and the transverse drainage ditch is to facilitate the filtration of debris in the drainage at equal intervals, thereby sharing the debris that subsequent filtration structures need to filter, preventing rapid clogging, and also making it easier for cleaning personnel to quickly locate cleaning points.
